I hope it’s not another case of buy it, try it, and then put it on the shelf.

Hi Larry. I have a 2010 version Drag Pak / 392.
I was really surprised with mine that I couldn't find a dual spring to work with the Heads & T&D Rockers. I used PAC 1427, which is their BBC Stock Eliminator Conical Spring. It's pretty beefy with 500# open and is stable up past 8300 RPM. But it's a single.
I sure would like the security of a dual.
